Captain Rocky, the leader of Epsilon ARC squad. After the switch to Phase 2 (Ep. III) clone trooper helmets and armor, he only accepted the new armor. He left his helmet exterior the same, but had an engineer update the HUD inside it. His Clone Trooper code is Alpha-112

Cool. Response to your comment. I've never seen this before so i'm sorry that they look similar. Pluse yours is a clone and mine is a mandalorian. another difference. so please don't be so quick to anger. THANKS! :D
